contrary to the conspiracy theories of David Icke, my personal definition of reptilian is:

people who act not of this world, they are usually wiggers and juggalos. they're English is slurred and they usually use phrases like "get some". they tend to throw up in random places, probably due to the fact that they're not use to our atmosphere, or all of the Earth drugs they've consumed that evening. they have a variety of faces, all Reptilian.
